Hey. First post here! I want to share a quick video I did when fixing the fan speed resistor on my 2007 GU.
The symptom was that the aircon/heater fan suddenly would only work on full blast. The lower settings (1-3) were just non-functional.
I learned that there is a resistor under the glove bx that is responsible for these settings. It has a fused link that can deteriorate with age and burn out. Its just a matter of replacing this link to get the fan speeds working again.
Finding the resistor is easy and you can see where it goes at the end of the video.
Check it out and let me know what you think....
